Being Rodolphus girlfriend meant having to visit his family. You didn't expect it, but his father had invited you to their Manor during spring break. Even Rodolphus was surprised at first, but as his father explained by letter, he seemed to have taken you seriously and actually wanted a relationship. And you were a pureblood. With money. That was what mattered to his father the most. Even if reluctant, you accepted (Didn't have much choice actually-)

"Dear.. please, calm down. It's fine!"
